Abstract (en)

[origin: WO9959778A1] An abrasive article is formed having a barrier coating coextensive with and interposed between a backing and an abrasive coating. The hardened barrier coating essentially eliminates penetration of the abrasive coating into the backing, especially volatile materials. The barrier coating comprising as starting materials a water-borne resin that upon hardening forms a crystalline or semi-crystalline polymer, a major polyfunctional cross-linking agent, and at least one minor polyfunctional cross-linking agent. The minor polyfunctional cross-linking agent enhances the attachment of the abrasive coating to the barrier coating.
